NFDM-437 I was made to cum until my balls were dry by the beautiful swim coach. Uminari Sakuru

Film Introduction

Mr. Tanaka, who joined the swimming club with no members at all, was enthusiastic about being able to monopolize the guidance of the beautiful coach, but the coach's competitive swimming suit is so sexy that his lower body is unintentionally flattering. The coach finds it, and he is forced to ejaculate many times, saying, "I can't teach you while you're dumb."
